WATER-MOTOR.

Application filed July 14, 1919.

T0 f/,ZZ whom it may concern.'

Be it known that I, KYLE H. ANDERSON, a citizen of the United States, resident at Echo, in the county of Umatilla and State of Oregon, have invented certain new and useful Improvements in Water-Motors, of which the following is a specification.

The present invention rela-tes to improvements in water motors, designed particularly for use in slow moving or flowing streams, and embodying instrumentalities for transforming an oscillating movement of a lever mechanism actuated by weight of water, into a continuous rotary motion, and provides an inexpensive source of power for running an irrigating pump, etc., where only a slow motion of the mechanism is required.

rIhe invention involves the utilization of a hollow buoyant tank adapted to be filled with water, which when ldaded, by its own weight imparts a working stroke to an oscillatable lever, and which tank is automatically emptied at the end of its working stroke, so that by its buoyancy the tank is returned to position to be again filled with water for a successive working stroke.

In the accompanying drawings one complete example of the physical embodiment of the invention is illustrated, the parts being combined and arranged according to the best mode so far devised for the practical application of the principles of the invention.

Figure 1 is a top plan view of the apparatus involving the invention.

lP ig. 2 is a sectional view of an inclosure for retaining water, showing the apparatus in side elevation partly broken away.

Fig. 3 is an enlarged View, partly in section, of the outlet valve of the buoyant tank, and connections.

In the preferred embodiment of the invention as illustrated in the drawings I have utilized a barrel, 1, of usual construction as the buoyant tank, it being understood that this vessel is shown as a convenient and comparatively inexpensive receptacle or tank, for the purpose. The tank is secured near the end of an oscillatable lever in the nature of a long tube or pipe 2, which has at 3 an opening into the tank at its upper portion, and at or near its opposite end the lever is provided with a pivot bearing a so that it may oscillate in the supporting bracket 5 provided therefor. f

Specification of Letters Patent.

Serial No. 310,570.

The long arm of the lever is designed to move between a pair of parallel, curved, uplright guides 6, preferably made of angle .iron strips and secured rigidly to the retaining wall 7 of the inclosure in which the water for the buoyant tank is contained, the water line being indicated at W. L. in Fig. 2. The buoyant tank is adapted to swing the lever on its pivot, and the upward movement of the tank is governed by mechanism actuated by contact with the stop pin 8 between the two angle irons of the lever guide, and preferably this pin is so located that the tank does not rise to the extreme position on the surface, permitted by its buoyancy,

in order that the water may enter the tankto fill it. In Fig. 2 the tank is shown in dotted lines, as still submerged, although at the extreme of its uplifted position, and also in this figure the tank is shown in full lines at its lowermost position where it is held by the locking latch 9 engaging the keeper 10, which latter is a bracket fixed on the wall T of the water inclosure.

The tank is adapted to swing with the oscillatable lever between the two extreme positions indicated in Fig. 2, its idle stroke being the down stroke that is caused by the illing of the tank through an inlet member 11 fastened by its flange 12 about an opening through the underV wall of the tank. The member 11 is normally held closed by theI valve 13 in its seat 14 in the head of the `member 11 and a spring 15 holds the valve to its seat as in Fig. 3 where the spring is shown interposed between the valve and a yoke 16 therefor.

The valve is opened, when the empty tank rises to its proper height by the action of a trip lever 17 pivoted at 18 on arigid arm or support 19 on the tank and connected by link 20 and push pin 21 with the bell crank lever 22 pivoted at 28 in the member 11. The link pin 21 passes through and is supported in an opening in the wall of the mem ber 11, and the bell crank lever against which the pin pushes is pivoted at 24 to the stem 25 of the valve. The action of this valve opening mechanism will be evident when the rising tank causes the trip lever to engage and swing around and hold the pin 8 in the guides 6, to push the valve open against the tension of the spring 15 as understood.

The valve is held open so that water may enter the tank, forcing the air therefrom through the lever pipe 2 which is open to the atmosphere at the end 2, .and the illing tank, by the weight of the water and its own weight, sinks to the lower position, making the idle stroke of the lever, and at the end of this stroke, the valve is automatically opened as will be described, while the tank is held or retained by the latch 9.

In the bottom of the water receptacle or inclosed area, la concrete base or struc-ture 2,6 isprovided through which a spillway 27 passes, vopening outside of the wall 7, and y:at its inner end fashioned with a valve seat -28for the :ontwardily opening valve 29 which is held normally closed by the spring 30 beneath it,'and the stem of the valve, as 3l,V @when the valve is closed, projects -up and through the valve seat 28.

YThe lval-ve 29 and lits stem 3l are located directly in the path of movement Iof the stem `25-of the valve 13, and the spillway is vprovided with .-an annular shoulder 32 forming ,.-a seat .directly'in the 1path of the member ll carried vby the tank. Thus, as shown in 'F ig. 2 the tank has descended, of its Iown weight, :to its lowermost position and is locked-'bythe latch i9, the memberv 1l is engaging 'the shoulder orseat 32 of the spi-llway clos-ing the spillway against communication with the anterior of the v v`tacle,fand the two valve stems 25 and 3l are water recepengaged, lifting their valves or removing their valves from their seats. Under these conditions water 1s free to pass from the tank through .the member l1, two valve seats,

andthe spillway out through the open end of the spiillway, to render the `tank once more buoyant after the water has flowed'therefrom.

:The emptied tank, however, remains held or yretained in lowered position until the latch 9is released, and this release is accomplished-'through the connecting rod 36,

arm 37 and .eccentric 38, the latter cna shaft 39 having a sprocketwheel 40 connected by sprocket chain 4l to a similar sprocket 42 .on theshaft 43. The .shaft 43 is the main shaft of the actuating mechanism and is driven from the short arm of the lever pipe thnough the pivoted link 44 on the lever and thegpivoted arm 45 on the shaft 43. The arm 45 `carries -a pawl or dog 46 which engages the ratchet -wheel47 on the main shaft 43, .and it will readily be seen that the moveinent of the short arm of the pipe lever will gturn the ratchet wheel in one direction, step ibyfstep-with the rising and falling of the tank, the quick upward swing of the long arm of the lever being the working stroke which turns the ratchet wheel through its ratchet or pawl connection. The throw of thepawl may be adaptedV or altered by moving the pivotal connection 48 to selected holes 49 in the arm 45, and the action Vof this ratchet mechanism results in turning the main shaft in-.one direction to operate a pump or other device as described, the

momentum being stabilized by a ily wheel Vas usual.
